Hi and a big thank you for the teachings.. please i want to understand example question 5 on the multiplication of matrix. is there a mistake in imputing the dimensions? i.e second row thanks
A small mistake 😅 the version of matrix C you used in your calculation was different the the Matrix C as it was written on the left board. Position 3,2 is changed.
I derived formula for coefficients of characteristic polynomial using matrix multiplication, trace and some basics about symmetric functions Soon you will record something about matrix inverse Have you read Knuths book The art of computer programming vol 1 There is algorithm for matrix inverse
@@PrimeNewtons I know how to inverse matrix by transpose of cofactor matrix or by elementary row operations but I would like to see explanation of algorithm which can be found in Knuths book Interesting pages are (p 303 , p 307)
what you wrote as C in your instructions at the beginning (above the compute section) is not what you wrote when you worked out C squared, the third column does not match so my answer was different for my third column.
im so glad i found this channel
i actually understand alot of stuff i have been struggling in uni now tysm
it was so simple i have seen this video before my exam and get 92.5% out of 100% .Thanks :)
Wow, great video
Fantastic ❤
Prime Newtons multiplies my knowledge of math! 😊
Thank you soo much sir u are really a great teacher.
I have a love-hate relationship with matrices. They're unquestionably useful, but I always feel like there's got to be a better way.
Don't hate. Only love ❤️ 😍
best math teacher!!

That was a mistake. The matrix was incorrectly copied from the list i made at the beginning. But the multiplication was correct.

I see you already got a comment on this. Your videos are amazing and I believe you are one of the best math teachers on TH-cam, just saying!
I want to understand Saras Diagram through your class. Please sir.

Waiting for the book to arrive!

😮 You are correct. That was a mistake. I copied incorrectly.
